Application filed .Tune 9,

To all whom t may concern.'

Be it known that I, FRED C. WHI'rEHoUsE, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented new and useful Improvements in l/Veather Strips, of which the following is a specification.

This invent-ion relates to weather strips especially adapted for use on doc-rs and windows. f

An important object of the invention is to provide a weather strip which may be applied to the standard sash without mari-ing the appearance of the same and without interfering with the freedom of movement o-f the sash. v

A further object is to provide a. weather strip which will positively exclude dust and air. l

A further and equally important object of the invention is to pro-vide a weather strip which may be applied without theexercise of unusual skill and which is so constructed that a constant and air tight connection is maintained between the parts.

Also, an important aim of the invention is to provide a weather strip having means whereby to permit of a limited lateral movement of the sash.y

Other objects and advantages will be apparent during the course of the" following description. i y

In the accompanying drawing forming a part of this application and in whichlike numerals are employed to designate like' parts throughout the same,

Figure 1 is a perspective of the improved weather strip applied; i

Fig. 2 is a group perspective of the weather strip;

Fig. 3 is a horizontal sectional view through the weather strip, the female member of the same being shown in the position it occupies immediately prior to being at-` tached to the window frame;

Fig. 4 is a. horizontal sectional view taken on line 4 4 of Fig. 1, and i Fig. 5 is a detail transverse sectional view illust-rating the means to establish an air tight connection between the upper "and lower sashes. i

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates a window frame having spaced parallel jamb strips 6 between which the stiles 1924. serai No. 718,950.

of a sash 7 are slidable. Itmight be said that the spaced parallel jamb strips 6 kdetine pairs of grooves within which the edge portions of the sash are 'slidable' The invention forming the subject matter of this application resides in the provision of simple and reliable means whereby a dustand air tight connection is'established between the sash and the frame and to this end certain of the j amb strips 6are provided with angle-shaped metallic strips 8. 4Figs.

1 and 2 illustrate that each angle strip 8 is provided with an attaching flange 9 having spaced openings 10 for the reception `of small nails or other suitable fastening devices. The flanges 9 are secured flatly in contact with the jamb strips 6 andy the flanges 11-of the anglestrips 8 extend inwardly into overlapping relation with the stiles of the several sashes.

` One edge portion of each flange 11 :is

rolled to provide a rounded bead 12, whichas plainly illustrated in Figs. 3 and 4, is received between the co-acting sides 14 and 16 which atly bear against opposite sides vof the flange 11 and, there-fore, cooperate with i the same in establishing an air tight joint.

Also, the opposite sides of the bead 12 contact with the opposed sides of the beadre ceiving channel 20 so that an'eifective fourpoint contact is provided betweenihe two sections of the weather strip.

`Attention is especially directed tothe fact that the spring sides 14 and 16 normally haveaslight space between them and when the section 18 of theweather strip is tacked or otherwise secured to the stile of the sash this space is taken up and the edge portions of the sides 14 and 16 are more `firmlyr pressed into engagement with the bead ,12 and the opposite'y sides of the flange ll so that a constant tension is exerted. Itis thus seen that the fastening means 25 of the female member 18 not only connect the female member to the sash but also provide areliable means for maintaining al con stant spring tension between the parts.

A weather strip constructed in accordance with this invention may -be applied either to the inner7 outer or the intermediate jamb strips without interfering with the freedom of movement of the upper and lower sashes and without in any way marring the appearance of the saine. f

n Also, aweather stripconstriictedin ac. corda-nce with this .invention may be cgon'-,

veniently applied by an unskilled person by, merely tacliirg.y the several. sectionsin the proper place.l A' lii'nitedl lateral sliding movement of 'each sash may take-` place with.

the Weather out permanently distorting weather strip. However, the improved strip reduces-this lateral slid-ing. movement excluding strip 30' which has one edge por.-I

ltion offset and overhanging a second strip 32. secured to the lower rail of the upper sash. This connection between the railsof they' upper and lower sashesprovides an absolutely air7 dust, cinder and smoke tigl-itcon-nection between the sashes and, therefore, provides anfeffective means for sealing the windows.

rIhe invention form-ing the subject.v matter of this application can alsobe used in connection with doors.

It will be seen that the novelv weather. st rifpis simpleI to install, and requiresv no ygrooving or cutting of the sash for that purpose.

Once the outfit isfinstalled, tliefoi'ir-'poi-ntl contact referred to seals the sash inthe man1-` ner described, and. no further attention to the installation is-required. Having thus. described is clai-med is:
